Nuclear clock may keep time with the Universe

Nuclear clock may keep time with the Universe – A proposed new time-keeping system tied to the orbiting of a neutron around an atomic nucleus could have such unprecedented accuracy that it neither gains nor loses 1/20th of a second in 14 billion years – the age of the Universe. In a paper to be published in the journal Physical Review Letters – with US researchers at the Georgia Institute of Technology and the University of Nevada – Victor Flambaum and UNSW colleague Vladimir Dzuba report that their proposed single-ion clock would be accurate to 19 decimal places.
